To all whom it may canoe. lb.

Be it known that wejEnwARD J. DOLAN and Mr- CHAEL J.. TRACY, bothocitizens of the United States, and

residents of the city and county of Philadelphia, State .of Pennsylvania, have inventedcertain new'and useful Improvements in Acetylene-Gas-Burner Tips, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1.is a perspective view of a tip constructed The object of our presentinv ention is to produce a tip which, from a single exit, will produce from acetylene gas, a flat, as distinguished from a cylindrical,

flame and'without undesired deposits. We attain this object by means of theconstructionshdwn in the drawings and hereinafter described, it being understood that relative proportions and shape of parts may be varied considerably withoutdeparting from our invention. I

Our tip A is composed preferably of lava, steatite, or other suitable material. It may be secured to the pillar B connected with the gas pipe or other source of supply in the usual manner. The tip contains interrn'ediate-the gas inlet and gas exit'a chamber 0 essentially of elongated cross section, said cross section being preferably parallelogrammic in form (Fig. 4) and its interior having preferably the shape of a parallelepiped,

I the said chamber having in all cases, when the tip is in upright operative position, a centralmajor horizontal axis on the line 90-23 and its central minor horizontal axis on the line-y.'y, at right angles thereto (see Figs.

'3 and 4). The chamber 0 leads directly into the single gas exit-D of the tip which isalso essentially of "elongated shape, preferably parallelogrammatic, '(Figs.

3 and/1) and having also, in all cases, a central-major horizontal axis parallel with-the central major horizontal axis of said ch'amberand its central minor horizontal axis at right anglesthereto and parallel with the central minorhorizontal axis of saidchamber, (see Figs; 3 and 4), the centers of all of said axes being therefore in the same vertical'line which is rectangularly-disposed to each of said axes. 'The said exit may be conveniently formed by cutting downwards, from the top of the tip, a central cleft E disposed at right angles to the major axis of-said chamber until the latter is opened by said .cleft, said opening'being carried slightly 'below the 1 00f of the chamber, if desired. The said major axes of the chamber and of the exit are mutually parallel and the centers of said axes also lie in the "same vertical line which isrectangularly disposed to all of the said axes enumerated, and it is essen-' tial that said major; horizontal axis of thechamber shall be longer than said major horizontal axis of the exit" The said minor axes of the chamber and of the exit are also mutually parallel and the centers of said minor axes lie in a line at right angles to each of said axes, and it is preferable that'said minor axes be of 'equal length, though the chamber maybe a little wider than the exit, without preventing operation.

The operation of those portions of our tipheretofore described is as follows;-'-*tl 1egas, under pressure, passes into the chamberfrom the gas supply pipe, and thence through the exit. The aforesaid relative shapes, proportions and dispositions-of the chamber and the exit result in gas being directed through the exit into the atmosphere in angularly opposed convergent directions to a point where" the impingement of the opposing streams against each other imparts to the gas rising therefrom. the form of an extremely thin sheet in a plane.

disposed at rightangles. to the major axis of the exit,

whichsheet in burning produces the desiredfia't flame. Where acetylene, or other gases rich in hydrocarbon are peed, it is important to seat the base of said flame at a distance from said exit. 7 Any convenient, or well known; means. may be employed for thie but we prefer our device shown in the drawings, which consists in impartingto the tip, outside of the exit, a cleft E extending. completely across the tip as shown, freely open at top and both ends to the atmosphere, and, preferably,

exit D, thus avoiding injurious deposits of combustion. I "We are aware that flat flames have been produced by impinging against each other two oppositely directed streams of gas, but this has hitherto required two sub stantially distinct gas'e'xits with the resulting dilficulty of securing, and maintaining, required alinement.

' Our tip obviates such difficulty, and dispenses with parts, by its-saidconstru'ction, which produces the (lee sired'flatflame from gas delivered through a single exit,

from' a single chamber, both novelly shaped and disposed as aforesaid, so as to secure said result.

" carried below. theexit on both sides thereof. This-cleft I The much greater diffusing surface presented by our attenuated sheet of gas, as compared with a cylindrical jet of equakvolume, and the vorticesimparted bythe. spreadingpf the stream from the exit in the presence of unlimited access of air afiorded by the cleft insure a thorough admixture of the gas with air, this admixture Q assert filling the cleft above the gas exit whereby deposits of combustion are also prevented. The cleft also permits the as to be burned under small pressure, as when the gas is again turned on lull.

What we claim as new and desire to secure by Letters Patent is the following, viz:-

l. An acetylene gas burner tip comprising a single elongated gas exit and a gas chamber of elongated cross section leading directly into said exit the central major axis of said chamber being longer than and parallelwlth the central major axis of said exit, the centers of said axes belog in a line rectangular thereto, and means for seating the flame. at a point from said exit.
